TRACTION ATTACHMENT FOR CAR-WHEELS.

Specification of Letters Patent.

Patented Dec. 29, 1914:.

Application filed February 7, 1913. Serial No. 746,859.

To all whom it may concern Be it known that I, WILLIAM H. FIEN- .HOLD, acitizen of the United States, residing at Champaign, in the county ofChampaign and State of Illinois, have invented new and usefulImprovements in Tractlon -Attachments for Car-Wheels, of which thefollowing is a specification.

My present invention relates especially to the class of tractionattachment for car wheels, and the provision of a device of thlscharacter which when attached provides the same with a smooth, broadengaging surface, thus enabling the wheel to be propelled upon dirtroads or highways of simllar nature.

Car wheels now in vogue are constructed to operate freely upon theirsupporting rails, and in carrying out this requirement, the rims of thesame are provided with a peripheral flange to prevent lateraldisplacement. With this in view it is apparent that the wheels are unfitto travel upon dirt roads or other highways inasmuch as the flange cutsdeeply into the roadbed.

My invention, as above set forth, provides a traction attachment whichwhen connected to the wheels renders their engaging surfaces even, andcomparatively broader than usual. From this it is recognized that thewheels are rendered capable of traveling on streets and roads withoutruining the same, consequently rendering the cars suitable conveyingwagons.

With the above and other objects in view my invention relates to suchdetails of construction and in the arrangement and combination of partsas will be hereinafter fully described and specifically pointed out inthe appended claim.

In describing my invention in detall reference will be had to theaccompanylng drawings wherein is illustrated the preferred form of myinvention and in which;

Figure 1 is a side elevation of an ordinary car wheel showing myinvention disposed in connection therewith. Fig. 2 is an end elevationshowing one section of the traction device in engagement therewith. Fig.3 is a fragmentary view of my invention showing the method of attachingthe sections at their ends. Fig. 4 is a sectional view taken on line 4-of Fig. 3. Fig. 5 is a sectional view of my device illustrating a detailin elevation.

Referring now more particularly to the drawings wherein is illustratedthe preferred form of my invention, the numeral 10 designates the bodyportion of an ordinary car wheel which as is usual carries a hub 11. Thehub mentioned is of the ordinary type and is adapted for engagement withan axle 12. The wheel is equipped with the usual tread 13 which has oneof its margins extended to provide a peripheral flange 14:, which, asWell known, is adapted to abut the inner side of the head of the rail toprevent lateral displacement of the wheel.

While the Wheel above mentioned is of the usual form, it is to beunderstood that this has been shown merely to illustrate the applicationof the invention and that my inventlon is readily applicable inconnection with other different forms, and from this it 1s apparent thatthe above form is merely shown to illustrate the applicability of thedevice.

My invention consists more essentially in a pair of semi-circularsections 15, the adjacent abutting edges of which are enlarged as shownat 16 to provide suitable reinforcements.

To facilitate the attachment of the sections about the rim and flange ofthe wheel, the same are provided with cut-out portions 17 and 18,respectively, the first mentioned receiving the enlarged rim of thewheel while the cut-out portion 18 receives the flange as illustrated.This construction enables the sections to be snugly disposed about thewheel, so that their enlarged ends may abut as illustrated in Fig. 1. Toprovide means for securing the adjacent ends of the section together,the enlargements upon one of the sections are provided with openings 17'and transverse apertures communicating therewith. The other enlargementsare also provided with openings 18 and transverse apertures, the lastmentioned openings being comparatively larger than the other opening forthe reasons hereinafter mentioned. Bolts 19 are employed, which aredisposed through the transverse apertures mentioned, the head portionsof the bolts fitting in the openings 17 as is recognized. Nuts 20 arecarried within the opening 18', and engage the bolt in such a manner asto securely draw the adjacent ends of the sections together.Semi-circucured in place a continuous broadened rim is formed. Anysuitable means may be employed for securing the rim to the sections, butin the drawings I have shown bolts and nuts 22 and 28, respectively,serving this purpose. The bolts and nuts have proven very efficient inactual practice inasmuch as they prevent the accidental displacement ofthe rim portions, thus more readily assuring the entire operation of myinvention.

The sections 15 mentioned, may be constructed of any suitable material,either molded or cast metal if desired. Each section 'may be cast as aWhole, thus reducing the cost of manufacture of the device to a minimum.The rim portions 21 are further preferably constructed of steel or thelike metal, inasmuch as the same is constantly in engagement With therough and uneven surfaces of the road.

The greatest of stress is laid upon the simplicity of my invention, andit is thought that the advantages and novel features of the same Will becomprehended from the foregoing disclosure.

Such changes as are permissible by the subjoined claim may be resortedto Without departing from the spirit of my invention.

Having thus fully described my invention, What I claim and desire tosecure by Letters Patent is A device of the character describedincluding a pair of semicircular sections adapted for detachableengagement With each other the inner periphery of said sectionsconforming to the contour of a car Wheel, and a rim carried on the outerperiphery of said circular sections for the pur-- pose specified.
